From the Ilford video by the Ilford Master Printer, Darkroom Dave, it would appear that he does ignore the G5 filter factor and simply uses the 6 secs from his test strip at G2.5 split as 3 secs and 3 secs for G0 and G5
So I assume that he has found a simple formula which effectively only requires the G0 and G5 to be split equally. Easy to do and easy to remember
OK he does modify the print from this by using G1 instead of G0 and increasing the G5 by 1sec but essentially the core formula would appear to be a an equal split, ignoring the 2x factor for G5
I'll give this way a go and see what I get
It would certainly appear to simplify the Les McLean method
It is literally splitting everything in half, using G2.5( a halfway grade) then splitting the best time for that in half at the two extremes
